LOCK-STRIKE.

No. 830,624h

T0 all whom, it may concern: Be it known that I, HARRY P. TowNsEND, of New Britain, in the county of Hartford and State of Connecticut, have invented *a certain new and useful Lock-Strike, of which the following is a specification.

My invention relates more especially to that form of strike that may be designated as a combined strike andl lock and which is the object of my invention is to provide a combined strike and lock that shall be eX- tremely sim le and cheap in construction,

easily assem led, andI one that shall include a combined strike and lock bolt. A device in the use of which thesel objects may be obtained is 4illustrated in the accompanying drawings, in which- Figure 1 is aview, partly in section, through the case of a piano, showing my improve- Fig. 2 is a detail view, on enlarged scale, with the front plate of the lock-case removed and showing the parts in locked position. Fig. 3 is a like View, but showing the parts in an unlocked position. Fi 4 is a top or end view of the strike-bolt. ilig. 5 is a side View of the same. Figf is a similar view, but showing the bolt gin a position at right angles to that of Fig. 5. Fig. 7 is a perspective view of the face-plate. Fig. 8 is a perspective view of the strike-plate and attached bolt-case. Fig. 49 is an end view of the same. Fig. 10 is a top view of the device shown in Figs. 8 and 9.

In the accompanying drawings the numeral 1 indicates the strin cover of a pianocase, said cover having a ange 2 projecting from its under surface.

The numeral 3 indicates a cross-piece forming a part of the piano-case, and the numera 4 indicates the key-cover of the piano.

A lock-case 5 is mounted in the flange 2 of the string-cover, this casebeing suitably constructed with a cover-plate 6, having a keyhole 7. A bolt 8, located in the case, has two guide projections 9 10, located, preferably, at right angles to each other, The projection 10 coperates with a guide-stud 11, projecting from the back wall of the case. The bolt is also provided with a bolt-catch 12 common to this class of locks and adapted to pass through and engage underneath the strike. The bolt is also provided with shoul- Specicationof Letters Patent.

'ders 13 14. A key-pin 15 projects into the case from one wall thereof, and a cam 16 is mounted u on this pin. This cam bears bitlugs 17 and) 18. It also has a bolt-operating nose 19. The case is also provided with a plate 20, through which the bolt-catch projects, and a recess 21 is provided in the bolt. A spring 22 acts upon the cam under certain conditions.

A strike-plate 23 is secured to the edge of the cross-piece 3 and a strike-bolt case 24 is secured to the under siderof the plate. This case is of a size to receive the head 25 of the strike-bolt 26 and is provided on opposite sides with Vslorts 27 for the reception of the iianges 28 on `the strike-bolt. The engagement of these iianges 28 with the slots in the case 24 prevents a rotating movement of they bolt, but permits lengthwise movement thereof. The ends of these flanges 28 are preferably formed' on the arc of a circle. In theV construction of the bolt the iiange is at first of circular form, and it is then milled off with .together in any desired manner. I have found that different ways or means for securing the two plates together may besatisfactorily employed, and screws 30h, passing through the holes 23a and 30 and into the wood to secure the strike-plate, will serve as a means for securing the two plates in engagement, this manner of fastening being shown in Fig. 2 of the drawings. It will be noted that in the operation of the lock the bolt-catch 12, coming in contact with the flan e or projection 28, forces the bolt downfwarrgi and into engagement withv the keycover, 'thus locking the string-cover and the key-cover in position. the sides of the flange or rejection 28 forms a shoulder, which provi es a stop to engage The milling 0H of` the admission of said' bolt an A peculiar feature of my invention resides m the shoulder which is formed at the end of the strike-bolt, this shoulder being formed by reducing the end ofthe bolt, and by the term freducing is meant that the end of the bolt is so formed that its dimensions are-less, at least in one direction, than the dimensions of that part of the head located immediately thereunder.

It is obvious that the details of construction may be departed from to a greater or less extent without avoiding'the invention, and I do not, therefore, desire to limit myself to the exact details' shown and described herein.

What I claim as my invention, and desire to secure by'Letters Patent, ish

.1. In a lock-strike, a-.strike-plate,` a cylindrical casing mounted on the strike-plate, a bolt iitting within said casing, means for moving the bolt lengthwise, means for preventing rotation of the bolt, and a face-plate attached to the strike-plate and havin an opening for forming a stop to limit its movement.

2. Ina lock-strike, a strikelate, a casing mounted on the strike-plate, a olt having an engaging projection to prevent rotary `movement thereof and a shoulder for engagement with a face-plate, means for moving the bolt lengthwise, and the `face-plate attached to the strike-plate and havingl an opening for the projection on the bolt.

3. In a lock-strike, a strike-plate, a casing secured to the strike-plate and having a slot, a bolt mounted in the casing and having a projection fitting said slot in the casing and a `shoulder adjacent to said projection for engagement with face plate, means for moving the bolt lengthwise, and the faceplate secured to the strike-plate and having an opening for the projection on the bolt.

4. Ina lock-strike, a strike-plate, a casing mounted on the strike-plate, a bolt located within said casing and having a projection on its end with parallel sides an ends formed on the arc of a circle and a' shoulder for engagement with a face-plate, means for moving the bolt lengthwise, andthe faceplate having an opening fitting the projection l on the end of said bolt.

5. In a lock-strike, a strike-plate, a facej plate attached thereto, a casing mounted on the strike-plate, a bolt located within the casing and having a projection ittin an opening in the face-plate, and a shoi/il er to abut thereagainst, means for holding the bolt in engagement with the facelate, and a shank from the bolt projecting t rough the wall of said casing.

6. -A strike-plate, a casing connected therel with and having an opening in its side for the reception of the end of the bolt of a lock, a

plate and a shoulder abutting against the under surface thereof, the opposite end of the strike-bolt projecting through the strike-bolt casing to engage and lock a movable part having a socket for the reception of the end of the bolt projected from the casing.

S. A strike-plate, a ycase. secured to the strike-plate, a bolt having at its end a reduced portion forming a shoulder, means for moving the bolt lengthwise, a separatelyformed face-plate attached to the strike-plate Aand having an opening for the reception of the reduced portion of the bolt and forming a stop to engage said shoulder, and means for securing the face-plate and the strike-plate together.

9. In a lock-strike, a strike-plate, a casing mounted on the strike-plate, a bolt having at its end a reduced non-circular projection forming a shoulder,` means for moving the bolt lengthwise, a separately-formed faceplate attached to the strike-plate and having an opening corresponding in shape to said reduced portion 0f the bolt, said face-plate forming a stop to engage said shoulder on the bolt, and meansY for securing the face-plate f and the strike-plate together.

10. A strike plate, a' casing connected therewith and having an openin in its side for the reception of the end of t e bolt of a lock, a strike-bolt located within the casing in position for engagement by the bolt of a lock and having a part to lbe projected through the opposite end of its casing to engage and lock a movablepart having a socket for the reception of said projecting end, and means for holding the bolt at one limit of its play. a

1 1. A strike-plate and .a casing connected therewith, said parts being arranged to receive and engage the end of the bolt of a lock,

a st rike-bolt located Within the casing a'nd adapted to be engaged by the bolt lof a lock and having a projection through the opposite end of its. casing to lock a movable part, and a movable part to be engaged by said projection.
